I'm currently using BES 4.1.6 we have about 47 users. Last week we upgraded our phones to BB Bold. Now, some of the user are experiencing their email from outlook not showing up on their phones, so the short term fix has been to remove the user from BES and add them again. I think that we may need to upgrade our BES to BB express....does anyone think this will work. If so let me know.

Don't think so when I looked on the about section of the device it didn't seem to have it.
Here is what I do have: Specs

smartphone 3G,CDMA, WiFI
6.0 Bundle 1741(v6.0.0.431, Platform 4.40.315)
3G Bands1
Branding Ver. 1.0.105.480g
